DeltaPP may predict cardiac index responses to PEEP and fluids in ventilated acute lung injury; leaves open need for prospective validation before guiding care.
Does the respiratory change in arterial pulse pressure (DeltaPP) predict the hemodynamic effects of PEEP and fluid loading on cardiac index in ventilated patients with acute lung injury?
In ventilated patients with acute lung injury, respiratory changes in arterial pulse pressure (DeltaPP) can accurately predict and assess the hemodynamic effects of PEEP and fluid loading on cardiac index.
